Twenty-four solar terms are the achievements of ancient people in China. Why are they expressed in the west instead of in the lunar calendar?

The 24 solar terms are subject to the lunar calendar, which is beyond reproach.

In addition to the moon orbiting the earth for more than 29 days, the lunar calendar also takes the earth orbiting the sun for more than 365 days as a one-year adjustment goal, and adopts the method of' seven leaps in nineteen years'. Therefore, the lunar calendar is a scientific chronological method that takes into account the sun, the earth and the moon.

According to the solar calendar, the earth revolves around the sun for more than 365 days a year. This makes the lunar calendar and the solar calendar have something in common. The 24 solar terms of the lunar calendar strictly record the relationship between the sun and the earth on a certain day, which makes the dates such as Tomb-Sweeping Day, vernal equinox, winter solstice and summer solstice coincide with the solar calendar.

To put it simply, the 24 solar terms in the lunar calendar represent the relationship between the earth and the sun, and the solar calendar also takes one year as the time for the earth to go around the sun, which is exactly the same.

Well, that's it,
